INVENTOR ATTORNEY Reisauedgoct. 21, 1930 UNITED STATES PATENT OFFICEJOHN AUGUSTUS MCCARTHY, OF ST. JOSEPH, MISSOURI, ASSIGNOR, BY'ML'SNELASSIGN- MENTS, TO THE PATENT AND LICENSING CORPORATION, OF BOSTON,MASSACHU- SETTS, A CORPORATION OF MASSACHUSETTS SHINGLE Original No.1,670,469,

This invention relates to improvements in shingles of the flexiblecomposition type and more particularly to improvements in shingles ofthis character, formed with locking 5 means for holding down thefreeweather exposed portions thereof.

An object of the invention is to provide a shingle or shingle striphaving locking means integrally formed in the shingle and 10 designed tocooperate with portions of overlapping shingles for securely retainingthe projecting free weather ends of the shingle against curling or beingraised by wind pressure.

A further object of the invention resides in the provision of a shinglestrip having integrally formed locking means so constructed as to beeasy to manipulate when the shingles are being laid on a roof, andeflicient in operation after they are laid, and interlocked one withanother.

The invention will be best understood from a consideration of thefollowing description, in view of the accompanying drawings forming apart of the specification. It is to be understood, however, that theinvention is not confined to the disclosure, being susceptible ofsuch'changes and modifications.

as will define no material departure from the salient features ofthe-invention, as set forth in the claims hereunto appended.

In the drawings Fig. 1 is a view in perspective showing a strip shingleconstructed according to the invention, together with its associatedoverlying shingle strip.

F ig. 2, is a perspective of a section of roof equipped with shinglestrips embodying the invention.

Fig. 3, is a section taken along line 3+3 of Fig. 2.

Referring more in detail to the drawing, the numeral 1 indicates theupper or main body portion of the shingle strip, and numeral 2indicates. the tabs projecting from the lower edge of the body portion.As shown 011 the drawing, the tabs are of semihexagonal shape havingside-edges 3, and are spaced apart by complemental recesses 2; theshingle strips as thus constituted being cut dated May 22,-1928, SerialNo. 234,705, filed November 21, 1927, Application 101' reissue filedDecember 19, 1929. Serial No. 415,317.

from a sheet or roll of roofing material in a well known manner suchthat waste is eliminated.

Adjacent the upper side corners of each of the tabs, the body portion isformed with anchoring receptacles or ears 4 extending laterally beyondthe upper side corners of each tab. These anchoring ears are formed byproviding angular slits 4;, 4 in the body portion adjacent the upperside corners of the tabs.. The slits 43 extend preferably at rightangles to the lower weather-edge of the body portion from points.laterally of the upper extremities of the edges of the-tabs. The slits 4at'the opposite sides of each tab, extend in opposite upwardly inclineddirections from the upper extremities of the slits 4, to a pointlaterally inward of the upper extremities of the edgesof the tab, and inthe plane through which the side edge of a superposed tab passes.

The receptacles or anchoring ears as thus formed are adapted to overliethe lower side corners of the tabs of a superposed shingle strip whenthey are assembled in courses on a roof, to thus effectively retain thetabs in flatwise position and prevent the free ends thereof from curlingor being'raised by wind pressure. l

The shingle strips constructed as aforesaid may be laid on a roof in thecustomary man ner, it being necessary merely ,to insert the lower sidecorners of each tab beneath the manipulable interlocking means whichper-i mits the lower side corners of the tabs to be properly insertedbeneath the anchoring ears, by a downwardmovement, with substantially noloss of time by the workmen applying the shingles to the roof.

I claim as my invention:

1. A strip shingle having a body portion and a plurality of equallyspaced tabs projecting from theweather side edge of the body, the bodyportion being formed at eachv side of each tab, with an angular slitforming anchoring ears in the body portion laterally adjacent each ofthe upper side corners of each tab and adapted to overlie and hold 100down the lower side corners of the tabs of a superposed strip when thestrips are assembled in courses, said slits and the anchoring earsformed thereby being arranged to permit the lower side corners of thetabs of an overlying strip to be inserted beneath said anchormg ears by-a downward movement of said overlying strip.

' 2. A strip shingle having a body portion and a plurality'of equallyspaced'tabs projecting from the Weather side edge of the body,.the bodyportion having right and left angular slots forming angular'receptaclesbetween the tabs of a strip and the tabs of adjacent strips;the firstleg of said angular slot being positioned at an angle to theweatherside'edge of the body; and the second leg of which extends at anangle to the first leg from its inner end in a straight line directiontoward the center between the tabs of a superimposed course of tabs, andterminating at a point in a plane of which the side edge of asuperimposed tab passes through, when the strip shingle are assembled incourses.

'3. A strip shingle having a body portion and a plurality of equallyspaced tabs projecting from the Weather side edge of the body, the bodyportion having right and left angular slots forming angular receptaclesbetween the tabs of a strip and the tabs of adjacent strips; the firstleg of said angular slot being positioned at a right an le to theWeatherside edge of the body; and the second leg ofwhich extends at anangle to the first leg from its inner end in a straight line directiontoward the center between the tabs of a superimposed course of. tabs,and terminating at a point in a plane of which the side edge of asuperimposed tab passes through,

When the strip shingles are assembled in courses.

JOHN AUGUSTUS MCCARTHY.
